The whistle type electric kettle is made of stretched aluminum plate, and the electric heating element adopts a submerged nickel plated steel sealed electric heating tube. The electric heating tube is installed at the bottom of the kettle, and a heat-resistant sealing ring is padded at the junction with the kettle body to prevent water leakage. This type of electric kettle is equipped with a strip shaped vibrating spring plate buzzer (air flow vibrating whistle device) on the lid, which will sound when the water temperature reaches 100 ℃ or above. Due to the fact that this type of kettle is generally not equipped with a temperature limiting controller, it is necessary to manually cut off the power supply. This type of electric kettle has a simple structure and low price, and is widely used in residential households.
